The present invention relates to a ram for a rubber compound mixer which mixes rubber used for a tire by mixing various materials necessary for the manufacture of a tire, and more specifically, to a ram for a rubber compound mixer, capable of reducing variation in specific properties per a batch of rubber compositions produced through the mixer. For this, the present invention relates to the ram (1) for a rubber compound mixer which is connected to a drive shaft (4) which presses rubber rubbers poured into a mixer by moving up and down by a hydraulic cylinder (3). The ram (1) comprises a central ram (1a) and auxiliary rams (1b) which are arranged on both sides of the central ram (1) and move up and down by an auxiliary drive shaft (4a). |
